This study provides a comprehensive survey of the complex pattern of nucleotide substitution in the control region of human mtDNA, which is of central importance to the studies of human evolution. A total of 1229 different hypervariable region I (HVRI) and 385 different hypervariable region II (HVRII) sequences were analyzed using a complex substitution… (More)

144 nature genetics • volume 26 • october 2000 The retrieval of mitochondrial DNA (mtDNA) sequences from the Neandertal type specimen from Feldhofer Cave in western Germany1,2 made possible a comparison of DNA sequences from an extinct hominid with those from modern humans. Recently, a second mtDNA sequence from a Neandertal child found in Mezmaiskaya Cave… (More)

This paper describes the organisation of a database for human mitochondrial control-region sequences. The data are divided into three ASCII files that contain aligned sequences from the hypervariable region I (HVRI), from the hypervariable region II (HVRII), and the available information about the individuals, from whom the sequences stem. The current… (More)

Infection during the first trimester of gestation with rubella virus (RV) is highly teratogenic. Embryopathy is a frequent outcome of the primary natural infection with wild type RV during pregnancy while accidental immunisation with life attenuated vaccine has apparently little or no adverse effect. Although the nucleic acid sequence of RV is exceptionally… (More)

A maximum likelihood framework for estimating site-specific substitution rates is presented that does not require any prior assumptions about the rate distribution. We show that, when the branching pattern of the underlying tree is known, the analysis of pairs of positions is sufficient to estimate site-specific rates. In the abscense of a known topology,… (More)

HvrBase is a compilation of human and ape mtDNA control region sequences. Sequences and related information on individuals, such as from where the sequences were obtained, is stored in three ASCII files as described previously. Moreover, the collection is also available as Mac/PC database application with a graphical user interface. It can be accessed… (More)

Cave bears (Ursus spelaeus) existed in Europe and western Asia until the end of the last glaciation some 10,000 years ago. To investigate the genetic diversity, population history, and relationship among different cave bear populations, we have determined mitochondrial DNA sequences from 12 cave bears that range in age from about 26,500 to at least 49,000… (More)

Proteinase 3C of hepatitis A virus (HAV) plays a key role in the viral life cycle by generating mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, 3C binds to viral RNA, and thus influences viral genome replication. In order to investigate the interplay between proteolytic activity and RNA binding at the molecular… (More)

Preparative continuous free flow-isoelectric focusing has been used to separate at least three different components of intrinsic peptidyl-prolyl cis/trans isomerase (PPIase) activity from erythrocytes lysate. By adding chemical spacer molecules like glycine and Bicine to commercial carrier ampholyte mixtures the resulting pH profile was predictably… (More)

The trifluoroethanol (TFE)-induced formation of alpha-helical structures in the peptide hormone calcitonin (salmon) was studied using limited proteolysis combined with capillary zone electrophoresis. A low TFE content in TFE/buffer mixtures was insufficient to introduce secondary structure, but two Lys-Leu bonds were found to have become inaccessible to… (More)
